At Comic-Con, The CW announced that the big villain on the upcoming season of Arrow would be Ra’s al Ghul, a character so important to the DC Universe that he was played by Liam Neeson—a legitimately respected actor—in Batman Begins. Obviously, the show can’t top that now, which means it has to start filling out its cast with some characters who are a bit more obscure. Enter Medium’s David Cubitt, who—according to The Hollywood Reporter—is joining the series as Mark Shaw, also known as The Manhunter. No, not beloved Justice League member J’onn J’onnz, he’s the Martian Manhunter. And not The Manhunters either, that’s an army of evil robots. This guy is just The Manhunter. He has some kind magic staff and dresses like a robot. Confused? Welcome to the world of TV shows based on comic books.

THR says Shaw will be an A.R.G.U.S. agent with some kind of tie to Diggle, and the article makes several references to him being a “meaty” character who plays a “crucial” role. That probably means he’ll be a little more important than a one-off reference like Arrow’s version of The Royal Flush Gang or Firefly. Also, Shaw was a member of the Suicide Squad for a bit in the comics, so that ragtag group of assholes might show up again along with him.
